Transcription initiation involves the interaction of DNA-dependent RNA polymerase with promoters. In bacteria, this is a highly regulated process. Many regulators interact directly with the bacterial ...

We describe experiments aimed at establishing whether circular single-stranded DNAs can form promoters for bacterial transcription from small folded motifs. In vitro selection experiments were carried ...

Apathogenic clostridia, which have been genetically engineered to express therapeutic genes, will specifically target hypoxic and necrotic regions in tumors. This specificity can be improved further ...

Bacterial transcription is a production line of copying over genetic instructions from double stranded DNA to produce RNA, which is then used for the subsequent production of proteins that the ...

A pea aphid depends on a bacterial symbiont for amino acids it can't get from plants. The aphid, in turn, provides the bacterium with energy and carbon as well as shelter inside specialized cells.

Bacteria have evolved molecular strategies for regulating the export of toxic metals from their innards. Two independent studies now pinpoint the details of one of these strategies, which protects ...

Pharma Equity Group's subsidiary (Reponex Pharmaceuticals A/S) has received notification from the European Patent Office (EPO) about the decision to grant their patent for drug compositions for the ...

For pea aphids, the ability to go forth and multiply can depend on a single gene, according to new research. The gene isn't even in the insect -- it's in the tiny symbiotic bacteria housed inside ...
